This component is an ESD protection device manufactured by Will Semiconductor. It is designed to protect sensitive electronic equipment, such as computers and smartphones, from electrostatic discharge (ESD). The device is in a dual flat no-lead (DFN1006-2L) package which reduces its form factor and makes it easier to install in tight spaces. The component is labeled as ESD5451N-2/TR on the device and is ROHS compliant. It offers excellent ESD protection up to 15 kV per the IEC61000-4-2 standard. Its low capacitance between the I/O and the ground pins also helps reduce signal distortion from ESD. It is suitable for a wide range of applications including consumer electronics, automotive, medical, and military.
